SUBSOIL ATTACHMENT FOR PLO-WS.

Application filed May 16, 1914. Serial No. 839,009.

To all whom it may concern:

Be it known that I, EDWARD J FORNEY,

a citizen of the United States, residing at Greensboro, in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Subsoil Attachments for Flows; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

The objects of the present invention are to provide a convenient, cheap and effective means whereby a plow of usual construction embodying a mold-board and landside may be adapted for subsoiling either as an operation performed simultaneously with the operation of furrow turning, or as an operation succeeding the operation of furrow turning. I

A-further object is to provide a subsoiling attachment for ordinary turn-over plows which maybe quickly and easily adjusted or set to operative subsoiling position, or, when so desired, readily folded out of the way to permit the plow to be operated asa simple turn-over plow in the ordinary way. I j

The invention consists in certain novel details of construction and combinations and arrangements of parts all as will be now described and pointed out particularly in the appended claims. I

Referring to the accompanying drawings, Figure 1 is a side elevation of a plow having the present invention thereon, the subsoiling share being down in working position. Fig. 2 is a similar view looking at the opposite side of the plow, with the subsoiling share in elevated or folded position. Fig. 3 is a rear elevation; and Fig. 4 is a plan view of the attachment separate from the plow.

Like letters of reference in the several figures indicate the same parts.

The attachment of the present invention embodies in its construction a frame which is adapted to be clamped or otherwise securely fastened to the plow beam of an ordinary plow and to form the support and brace for a movable subsoiling share or shovel which will normally occupy a position behind and above the bottom level of the mold board and landside of the plow, but which is adapted to swing down into operative position where it will project below the bottom level of said parts for effectually breaking andlightening the soil in the bottom of the furrow.

7 As shown in theaccompanying drawing, which is a preferred construction, the frame embodies a bar A adapted to be attached at its forward end to the by a clip a. Said bar, the plow, occupies an inclined position with its rear end down behind the plow body and preferably projecting through between the lower portions of the handles. The other portion of the frame is formed by an angle iron G securely fastened to an intermediate portion of the bar A and adapted to occupy a substantially horizontal position projecting rearwardly from the plow beam and itis conveniently secured at its forward end to said beam by a clip a, although, as will be readily understood, other fastening means may be employed. The clip 0 not only secures the part O to the beam, but also operates to clamp the intermediateportion of the bar A so that the two parts of the frame are held firmly in position, and in order to give additional rigidity with some capacity for adjustment of the angular relation of the parts, they are connected at the rear end by an adjustable connection in the form of a long bolt D, the upper end of which is.

nuts 03, and the lower end of which is bent at substantially right angles and projected through one or the other of a plurality of openings in the end of the bar A, as at d.

The angle iron portion C of the frame at its'rear end, is provided with, a transverse bearing for a through-bolt e which constitutes a pivotal support for the standard of the subsoiling share or shoe. This standard is preferably formed of relatively heavy beam of the plow, as

when in position on adjustably held in the angle iron- C, by clamping the subsoiling. I

bar metal with its upper portion bifurcated to form arms E so as to embrace the part C of the frame, while the bar A projects through between the said arms. The lower portion of the standard below the bar A is curvedforwardly to'form a rigid seat for the share or shoe F of the subsoiling attachment. To give rigidity to the standard it is preferably braced by cross bolts and rivets f and the share or shoe is held in placebya bolt having a clamping nutF on its rear end-"provided with a tubular finger piece 7 adapted for the reception of a rod or other implement whereby the nut -may beturned for adjustment or removal of thesha-re. The two sides of the standard formedby the lower portion of the arms E are slightly separated for the admission of the shareholding bolt, and this construction provides a convenient means whereby the share maybe adjusted vertically so as to vary .to a considerable degreethe depth of The standard for the subsoiling attachment, as before seams pi'votally connected ,at its ,upper end'with the frame and is adaptedto swing from its elevated or-folded position shown. in Fig. 2, down to its extended or lowered position shown in Fig. 1. W hen'in the latter position it is subject to considerable strain but it is supported and braced'at a point'well below its pivotal attachment by the transversely extending end d. ofrthe bolt D, or if so desired, a transverse bolt or pinof any suitable character "may be located in one of the holes in the rear end of the bar A to accomplish the same result. The provision of a plurality of holes in the bar it permits of a variation in the angular position of the standard and its shareyso that it maybe setto draw into the ground to a' greater for less'degree as desired bv the plowman.

For holding the-subsoiling standard and its share in elevated or folded position, a catch H is pivotally mounted on the frame 'in position, to cooperate with one of the cross bolts in the standard when the latter is swung up into its folded or elevated position, and'the rear end of this catch is projected a suflicientdistance so that it may be readily'lifted by'the foot of the plowman when it"is desired torelease thesubsoiling device; although the weight of the catch will hold it in engaging position'with ample security until it isintentionally released as aforesaid. J i

. Obviously, the particular style and construction of the. framework of the subsoiling attachment may be, varied and adapted for connection with-plows of various types andstyles, but ineach instance itvis prefer- .able to have the frame offset laterally with respect'to the-longitudinal axisof the beam so as to bring the subsoiling share into the proper line of drift and to prevent the subsoiling share from working too closely to the landside of the furrow where it would meet with heavy resistance and possibly tend to cause the plow to drift into the previously formed furrow.

In operation, the subsoiling device may be used simultaneously with the mold board so that a furrow will be turned and the subsoiling accomplished simultaneously, but by properly setting the parts it is entirely practical to use the subsoiling device without turning a furrow.

With the present device the subsoiler may be thrown into and out of operation almost without effort on the'part of the plowman, a simple dragging of the plow real-wardly by the handles will ordinarily lift the subsoiling share and standard high enough for the catch to engage the same and when it is desired to throw it into operation the catch may be disengaged by kicking the same upwardly and allowing the subsoiler to drop down to operative position.

2. A subsoiling attachment for plows embodying a frame formed of substantially horizontal and diagonal members arranged in a vertical plane and connected together at their forward ends with means for attaching said frame to a plow beam,the frame being oflset laterally with respect to the longitudinal axis of the beam, a subsoiling standard pivotally connected with the substantially horizontal'member of the frame at a point in rear of the mold board and landside to swing in the plane of the frame and a stop on the horizontal member of the frame for limiting the downward and rearward movement of the standard.
